The success of the IP architecture is largely due to the simplicity, robustness and scalability that resulted from its the connectionless design methodology. As the Internet evolves it must support new services such as QoS and when extensions are made to the IP architecture to support such services, its basic connectionless model must be preserved to retain the scalability and robustness that made it so successful. In the past few years, with the Internet becoming the main communication infrastructure IP networks are faced with two challenging problems that require immediate attention: traffic, engineering and supporting guaranteed services providing efficient, robust and scalable solutions to these problems within the framework of the connectionless IP has become extremely important and urgent.
It is widely recognized that Traffic engineering (TE) mechanisms have to be added to the IP transport functionalities to provide QoS guarantees while ensuring efficient use of network resources. Traffic engineering is a network management technique which routes traffic to where bandwidth is available in the network to achieve QoS agreements between current and future demands and the available network resources. Multi-path routing has been proven to be a more efficient TE mechanism than Shortest Path First (SPF) routing in terms of proffit maximization and resource usage optimization. However the identiffication of set of paths over which traffic is forwarded from source to the destination and the distribution of traffic among these paths are two issues that have been widely addressed by the IP community but remain an open issue for the emerging generation IP networks. Building upon different frameworks, this thesis revisits the issue of multi-path routing to present and evaluate the performance of different traffic splitting mechanisms to achieve QoS routing in Multi-Protocol Label Switching (MPLS) and Wireless Sensor Networks (WSNs).

This book addresses the challenges and opportunities of information/data processing and management. It also covers a range of methods, techniques and strategies for making it more efficient, approaches to increasing its usage, and ways to minimize information/data loss while improving customer satisfaction. Information and Communication Technologies (ICTs) and the Service Systems associated with them have had an enormous impact on businesses and our day-to-day lives over the past three decades, and continue to do so. This development has led to the emergence of new application areas and relevant disciplines, which in turn present new challenges and opportunities for service system usage. The book provides practical insights into various aspects of ICT technologies for service systems: Techniques for information/data processing and modeling in service systems Strategies for the provision of information/data processing and management Methods for collecting and analyzing information/data Applications, benefits, and challenges of service system implementation Solutions to increase the performance of various service systems using the latest ICT technologies
Complex Social Networks is a newly emerging (hot) topic with applications in a variety of domains, such as communication networks, engineering networks, social networks, and biological networks. In the last decade, there has been an explosive growth of research on complex real-world networks, a theme that is becoming pervasive in many disciplines, ranging from mathematics and computer science to the social and biological sciences. Optimization of complex communication networks requires a deep understanding of the interplay between the dynamics of the physical network and the information dynamics within the network. Although there are a few books addressing social networks or complex networks, none of them has specially focused on the optimization perspective of studying these networks. This book provides the basic theory of complex networks with several new mathematical approaches and optimization techniques to design and analyze dynamic complex networks. A wide range of applications and optimization problems derived from research areas such as cellular and molecular chemistry, operations research, brain physiology, epidemiology, and ecology.
The availability of cheaper, faster, and more reliable electronic components has stimulated important advances in computing and communication technologies. Theoretical and algorithmic approaches that address key issues in sensor networks, ad hoc wireless networks, and peer-to-peer networks play a central role in the development of emerging network
Increasingly, modern medicine relies on so called traditional or ancient medical knowledge. Holistic practices such as adhering to proper diet, observing rules for appropriate behavior, and administering medical preparations are coupled with the latest technology and methods to treat the whole patient. In light of this trend, there is much to be gained from understanding of one of the oldest medical systems still in existence. Tibetan Medicinal Plants provides you a detailed analysis of how Tibetan plants are used in this centuries old system. The book opens with a summary of Tibetan medicine and covers the various habitats in which the plants are found. The main part of this volume encompasses 60 monographs listed by the Tibetan plant name. Each monograph consists of several chapters addressing different topics related either to the Tibetan or the Western approach. Most of the monographs contain a description of the macroscopic and microscopic characteristics of the used plant parts, and anatomical features of 76 plants are provided. Each monograph presents an overview of the known chemical constituents and pharmacological properties of each plant and describes their use in Tibetan medicine. In contrast to other publications on Tibetan medicine, where translations of the Tibetan terms are given in other languages, this book treats the Tibetan word as a technical term, keeps the Tibetan term and explains its meaning, lessening confusion by reducing the number of translations. Traditional Tibetan medicine has been in existence for centuries. Curative practices existed in the prebuddistic era, and the art of healing developed more than 2500 years ago. Tibetan Medicinal Plants provides a comprehensive overview of all plant types, thus making it easier to grasp the Tibetan concept. It gives you a comprehensive look at this centuries old science.
